final WearSharedPreference preference = new WearSharedPreference(context);
preference.put(getString(R.string.key_preference_photo_url), photoUrl);
preference.put(getString(R.string.key_preference_photo_title), title);
preference.sync(new WearSharedPreference.OnSyncListener() {
    @Override
    public void onSuccess() {
    }

    @Override
    public void onFail(Exception e) {
    }
});

Getting SharedPreferences value.

String beforePhotoUrl = new WearSharedPreference(this).get(getString(R.string.key_preference_photo_url), "");

Knowing change event of SharedPreferences value.

If you want to know change event of preferences by wear and phone, You can use 'registerOnPreferenceChangeListener'.

    @Override
    protected void onStart() {
        super.onStart();
        wearPref.registerOnPreferenceChangeListener(new WearSharedPreference.OnPreferenceChangeListener() {
            @Override
            public void onPreferenceChange(WearSharedPreference preference, String key, Bundle bundle) {
                if (!TextUtils.equals(getString(R.string.key_preference_photo_url), key)) {
                    return;
                }
                final String photoUrl = bundle.getString(key);
                // You can use changed photoUrl.
            }
        });
    }

    @Override
    protected void onStop() {
        super.onStop();
        wearPref.unregisterOnPreferenceChangeListener();
    }
